Electrical Energy Storage

One of the toughest challenges facing the energy sector is how to deliver low carbon energy without adding expense to household bills or hampering future security of supply. One possible solution is energy storage which can be used to store renewable energy when demand is low and to output energy during high demand periods.

Even if you have no intention to export power to the electricity network it is important that you notify us if the storage unit is operating in parallel with the network.

Small Scale Storage (≤3.68kW per phase) with no other generation

If you’re looking to install a small scale storage system where no other generation sources are in existence within the property, you should follow the ER G83 connection process.

As with other forms of electrical generation, you will need to charge the storage system using power from the electricity network. Installers should ensure that the property’s electricity supply is suitable for the connection of the additional demand and generation.

Small Scale Storage (≤3.68kW per phase) with other generation (≤3.68kW per phase)

Working in partnership with the ENA, a relaxation to the standard design rules of G59 has been developed to allow those wishing to combine a G83 generator with an energy storage device.
